AIMS: To compare healthcare costs in patients with non-inhibitor hemophilia A treated with Rurioctocog Alfa Pegol (FVIII-PEG) versus Antihemophilic Factor (Recombinant), FC Fusion Protein (rFVIIIFc).
MATERIALS AND METHODS: Administrative claims data from the Merative MarketScan Commercial (Commerical) and Medicaid (Medicaid) databases were used for these analyses. Males with non-inhibitor hemophilia A treated with FVIII-PEG or rFVIIIFc from 1 January 2016 to 31 March 2021 were identified (earliest treatment = index). Patients were required to have continuous database enrollment for six months before and after the index date. Follow-up was variable in length until disenrollment or study end. All-cause and hemophilia-related healthcare costs were reported per-patient per month [PPPM] and the average weekly dose during follow-up was compared between treatment groups. Generalized linear regressions were used to estimate multivariable-adjusted differences in total costs and weekly dosage in the two treatment groups.
RESULTS: A total of 131 FVIII-PEG (66 Commercial; 65 Medicaid) and 204 rFVIIIFc (111 Commercial; 93 Medicaid) patients were eligible. Mean age was 20.5 and 24.4 for FVIII-PEG and rFVIIIFc in Commercial and 14.9 and 17.5 for FVIII-PEG and rFVIIIFc in Medicaid. PPPM mean (standard deviations [SD]) total healthcare costs in Commercially insured patients were $35,868 [$21,717] for FVIII-PEG vs $40,424 [$25,882] for rFVIIIFc. Costs in Medicaid were $27,495 [$23,243] for FVIII-PEG vs $30,237 [$28,430] for rFVIIIFc. After adjusting for baseline characteristics, the costs for rFVIIIFc (vs FVIII-PEG) were higher by $5,215 in Commercial and $3,895 in Medicaid, but the differences were not statistically significant (p > 0.05). Similar findings were observed for hemophilia-specific healthcare costs. The adjusted mean weekly dose was 6,047 vs 4,892 IU, p = 0.21 for FVIII-PEG vs rFVIIIFc in Commercial and 5,549 vs 7,228 IU, p = 0.07 for FVIII-PEG vs rFVIIIFc in Medicaid.
CONCLUSIONS: Healthcare costs and treatment dosing were similar (p > 0.05) for non-inhibitor hemophilia A patients treated with FVIII-PEG and rFVIIIFc.
